3.5 Control levers, pedals
WARNING
When leaving the operator's compartment, switch control
lever lock switch to OFF position, raise the safety lock lever
to the LOCK position. If the control levers are not locked and
they are touched by mistake this could lead to a serious
accident.
If the safety lock lever is not raised in the LOCK position and
lock switch is not OFF, the control levers may not be properly
locked. Check that the situation is as shown in the diagram.
When the safety lock lever is being raised, take care not to
touch the work equipment control lever. If the safety lock
lever is not properly locked at the upper position, the work
equipment and swing will move, creating a potentially dan-
gerous situation.
When the safety lock lever is lowered, take care not to touch
the work equipment control lever.
In certain conditions it may be possible for the safety lock
lever to contact the left hand arm rest on the operator seat.
to avoid this, always ensure that the left hand arm rest is
stowed in the fully up position before operating the safety
lock lever.
Safety lock lever
The safety lock lever LOCKS the work equipment, swing, attach-
ment controls and travel functions.
This device is a hydraulic lock, so even if it is in the lock position,
the work equipment control lever will move, but the work equip-
ment and swing motor will not work.
